Demo3 Configurations

Demo3 Configurations
This document describes the various configurations and boards available for use with the Demo3. It also includes the part numbers of the Demo3 adaptor boards.
There are 4 Demo3 related boards.

• Demo3 (AGB2N0CS); the Demo3 baseboard. Its connector supports parallel, MIPI 2/4 Lane, and HiSPi connection without the need of the RJ45 cabling required for Demo2X-style connector and auxiliary board.
• Demo2X to Demo3 adapter (AGB2N0CS); connect old-style headboards and Aux boards to a Demo3
• Demo3 to Demo2X adapter (AGB3N0CS); connect new-style headboards to a Demo2X
• Demo2X headboard to ICP2 adapter (AGB4N0CS); special-purpose adaptor for ICP2 only.

A few definitions/abbreviations used in this document;

• Demo3; the USB3 baseboard (AGB1N0CS)
• D2-to-D3 adapter; Demo2X to Demo3 adapter (AGB2N0CS)
• D3-to-D2 adapter; Demo3 to Demo2X adapter (AGB3N0CS)
• D2-to-D3 ICP2 adapter; Demo2X headboard to ICP2 adapter (AGB4N0CS)
• D3 HB; a headboard with the new Demo3-style connector
• D2 HB; a headboard with the old Demo2X-style connector
• Adapter; generic term for a board that bridges between old and new style connectors
• Aux board; most likely the HDMI-LC, but any of the auxiliary boards that provides MIPI or HiSPi cabling that has a Demo2X-style connector
• <->; a physical connection

D3 HB <-> Demo3 (AGB1N0CS)
D3 HB <> ICP2 <> Demo3 (AGB1N0CS)
Most new headboards (e.g. AR0833, AR1330, AP1300 (ICP2) ) are built with the new Demo3-style connector. These are the "cleanest" configurations in that they don't require any RJ45 cables.
D2 HB <> D2-to-D3 adapter (AGB2N0CS) <> Demo3 (AGB1N0CS)
D2 HB <> Aux board <> D2-to-D3 adapter (AGB2N0CS) <-> Demo3 (AGB1N0CS)
To connect a Demo2X-style headboard to a Demo3, you'll need a D2-to-D3 adaptor board, the AGB2N0CS. This adaptor board has (2) RJ45 connectors for cabling to a Demo2X-style aux board.
D3 HB <> D3-to-D2 adapter (AGB3N0CS) <> Demo2X
D3 HB <> D3-to-D2 adapter (AGB3N0CS) <> Aux board <-> Demo2X
For use in connecting any Demo3-style headboard to a old-style Demo2X-style baseboard, or a Demo2X-style aux board. This adaptor board has (2) RJ45 connectors for cabling to a Demo2X-style aux board.
D2 HB <> D2-to-D3 ICP2 adapter (AGB4N0CS) <> ICP2 (D3) <-> Demo3 (AGB1N0CS)
This adapter is specialized for use with the ICP2 to connect Demo2X-style headboards. It is NOT interchangeable with the D2-to-D3 adapter (ABG2N0CS). This adaptor board has (2) RJ45 connectors for cabling to a Demo2X-style headboard.
D3 HB <> debug board (part number TBD) <> Demo3 (AGB1N0CS)
This TBD board brings out volt and tap-points from the Demo3 board.
And for fun, some other configurations that are possible;
D2 HB <> D2-to-D3 adaptor ICP2 <> ICP2 <> D3-to-D2 adaptor <> Aux board <> D2-to-D3 adaptor <> Demo3
7 boards. Why? To use an HDMI's larger internal capture capacity.
D3 HB <> D3-to-D2 adaptor <> ICP-HD <> Aux board <> D2-to-D3 adaptor <-> Demo3
6 boards. Why? To support Demo3-style headboards on ICP-HD.
